摘要： 为探究滴灌条件下设施甜瓜的耗水规律,开展了滴灌条件下设施甜瓜耗水规律灌溉试验研究。试验以田间持水量的55%、70%、85%作为灌水下限,分别设置了3个水分处理,每个处理设重复3次。试验结果表明,滴灌条件下设施甜瓜耗水规律为:从定植到果实膨大期,其耗水强度由低逐渐变大,到果实成熟期耗水量有所下降;在平均灌水总量为180mm的T2处理取得了最高产量27000kg/hm2;通过耗水量与产量回归分析,此次试验甜瓜全生育期最佳耗水量为218.47mm。设施甜瓜滴灌浇定植2次缓苗水以后至开花结果前无须灌水,进入开花-坐果期以后,以每周灌1次水为宜,灌水定额300m3/(hm2·次)左右可基本满足设施甜瓜所需水量,推荐灌溉定额为2250m3/hm2。

Abstract: An irrigation experiment was conducted to study the water consumption pattern of facility cantaloupe under drip irrigation conditions. The lower limits for irrigation were 55%, 70% and 85% of the field water holding capacity respectively, and three water treatments (T1, T2, T3), were repeated three times accordingly. The experimental results showed that under drip irrigation conditions, the water consumption pattern of facility cantaloupe was as follows: from planting to fruit swelling period, the water consumption intensity gradually increased from low to high, and decreased to a certain extent during fruit ripening period; The T2 treatment with an average total irrigation amount of 180mm achieved the highest yield of 27 000 kg/hm2; Through regression analysis of water consumption and yield of facility melon, the optimal water consumption for the entire growth period of cantaloupe in this experiment was 218.47mm. The facility melons required no irrigation from after the second slow-seedling watering at planting untill the pre-flowering and fruiting stage with drip irrigation. After entering the flowering fruiting period, it is advisable to irrigate once a week with a water quota of about 300 m3/(hm2·per application), which can basically meet the water demand of the facility melon. The recommended irrigation quota is 2250 m3/hm2.
